How to satisfy a philosophy essay rubric when juggling three assignments?

I'm a sophomore at a community college aiming to transfer to a four‑year school, and my philosophy professor gave a detailed rubric for a 1500‑word essay that’s due Thursday, but I also have a biology lab report and a history paper due that same week. I’ve tried outlining the essay early, but I keep running out of time to address the rubric’s criteria for argument structure and source integration. What strategies can I use to prioritize the rubric points while still finishing the other assignments on time?
